Download actions

Last Updated : Jul 05, 2015 |

There are several different scenarios which causes a terminal to be downloaded. These can occur as part of background maintenance activity or on demand from the SAT or from a station.

For the background actions described below, the terminal downloads automatically if a download retry flag for the terminal is set in software. This flag is set at the time translation is loaded at boot time, when the translation that affects the parameters of a terminal is changed as part of system administration actions, or when a port is inserted in software as a result of board insertion or translation change.

Automatic download actions

  1. System Reboot and restart

    A global download action is initiated when periodic maintenance tests begin after a system reboot and restart, regardless of whether the parameters have been downloaded previously.

  2. Periodic tests

    If the download flag is still set when periodic tests are run on a terminal, a download action occurs. This action is required in case a terminal could not be downloaded previously, because the terminal was off-hook when the:

    • System first booted

    or

    • Translations associated with downloadable parameters were changed.

      Note:

      It may take more than an hour for periodic tests to reach the terminal that needs to be downloaded.

  3. Terminal administration

    A downloadable terminal is automatically downloaded when translation changes associated with downloadable parameters are made as part of system administration. As shown in the previous table, these changes can be for a specified terminal or may be system-wide. If the change is for a system-level parameter, a background global update request must be submitted to download every programmable terminal.

    Note:

    This global update may take more than an hour for a system with several thousand programmable terminals.

  4. Port insertion

    Whenever maintenance software initiates a request to place a port into service, a terminal download action is begun on that terminal, if that terminal is programmable. This port insertion action occurs under the following circumstances:

    • A digital line circuit pack that is physically inserted into the system and has ports currently administered for programmable terminals.

    • A station port is added to the system by add station or change station.

    • A TTI port is activated.

  5. Audits

    As part of periodic maintenance, the Hardware Status Audit test queries programmable terminals to determine which levels and/or options are being used. If the reported values are not equal to the administered values, the system will initiate a terminal download action; however, this audit does NOT check the parameters used for softkeys.

  6. Activation of TTI

    A terminal is downloaded automatically when it is activated using the Terminal Translation Initialization (TTI) feature. Therefore no special user actions are required for TTI.

    Note:

    Plugging the station cord into a terminal does not automatically cause the terminal to be downloaded. If this terminal has factory defaults or if the terminal has been previously downloaded with parameters different than those desired, use one of the demand download actions described below to download the terminal.

Demand download actions

  1. Busyout and release command

    A maintenance demand busyout and release request for a station will cause the terminal to be downloaded regardless of its previous download status.

  2. Feature Access Code (FAC)

    A refresh terminal parameters FAC can be used to request a terminal download action. When this code is followed by a (#), the programmable parameters for the current terminal are downloaded when the terminal goes on-hook. When this code is followed by an extension, the programmable parameters for the specified station are downloaded.

    This refresh terminal parameters FACis assigned on the third page of the change feature-access-codes screen.

    A confirmation is returned if the download request is accepted. A busy tone is returned if the request is made from a different station when the target station is off-hook.

    As a result of an entry of a refresh terminal parameters FAC, the first three green call appearance LEDs on the 84xx 603x terminal are turned on for three seconds, if the station was successfully downloaded. This is not true for the 302B1 terminal.

    There is no visible display on a station for the other background or demand download actions. As described below, use status station and status attendant to check the download status of a specified terminal.
